Ruler (2.7K stars) solves the fragmentation problem of maintaining separate rule files for Claude Code (CLAUDE.md), Codex, Cursor, Aider, and 8+ other tools. Write once, Ruler syncs to all agent-specific formats. If you're switching between agents and your rules keep drifting, this saves real time.

The IDE market is fragmenting, and this week drew the sharpest lines yet. Cursor 3 launched as a rebuilt agent-orchestration platform in Rust and TypeScript, replacing the VS Code fork with an Agents Window for dispatching and monitoring multiple AI coding agents. Anysphere hi...
bradautomates/claude-video (v0.2.0, July 1) lets agents download, frame-extract, and transcribe any video via yt-dlp, ffmpeg, and Whisper, then hand it to Claude's multimodal Read (GitHub). It ships as an Agent Skill usable across 50+ agents: Claude Code, Codex, Cursor, Gemini...
Ruler is one of several answers to a real fragmentation problem: CLAUDE.md, AGENTS.md, .clinerules and assorted TOML variants all encode the same rules. Codex 0.147.0 imports Cursor-managed skills and syncs without duplicates. The Agent Skills spec at agentskills.io has roughl...
wanshuiyin/HERO-Anti-OverDefense went from creation to 68 stars in a single day. HERO is Hashing, Edge cases, Rubrics, Overbuild, and the claim is that agent over-engineering isn't diffuse but falls into four recognizable shapes suppressible with a portable prompt contract acr...
Stewardship moved to the Agentic AI Foundation under the Linux Foundation, with 30+ tools reading it natively: Claude Code, Copilot, Cursor, Codex, Gemini CLI, Windsurf, Devin, Aider, Amazon Q (BuildBetter). Claude Code reads AGENTS.md in addition to CLAUDE.md, which stays its...
A single markdown file. 56,000 stars. multica-ai/andrej-karpathy-skills gained 42,000 stars in one week, making it the fastest-growing repo I've tracked this year that isn't an actual software product. The file is derived from Karpathy's observations about LLM coding pitfalls....
